To all? whom it may concern:

Be it known that I, Gnonen A. Donnie, a citizen of the United States, and residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Heel-Building Machines, of which the 7 following, is a specification.

This inventlon relatesto machines for building heels.

bled heels, the heels being piled in the press and the whole being subjected to pressure until dry or nearly dry. Thepieces of scrap are entirely too irregular and ununiform in shape to be automatically assembled by mechanism, and therefore the, assemblingmust be done by hand. In order that the method of building heels from scrap or waste leather may be used economically, the apparatus must be so arranged that the lifts can be assembled rapidly and'by unskilled operators. In apparatus which has been heretofore used to a small extent, the lifts were assembled in a mold .and then secured by a. fastener. Such an apparatus, however, rendered the method entirely too slow to'be used economically for the following-reasons: Where the lifts are-assembledin a mol these lifts must be inserted in -a hole, which necessitates that each lift or piecebe.

dropped in place and the operator cannot therefore use both hands at oncefor placing the lifts in position, since the small. space. in the mold will notpermit such operation. The result is that the assembling operation has been performed heretofore toalargeextent by assembling-the lifts againeta small gage on a table, and the fastener-was aslo drivenby hand. This. is, of course, anexceedingly slow and expensive: methodjand requires that. the operators first assemble the heel-by hand, and then pick up a ham: mcr and drive the fastener.- a

One of the objects of this invention therefore is to construct a machine-in which the lifts can be rapidly assembled and fastened to ether, the positioning means whereby the 11 ts are assembled, being so constructed that the operator can use both hands atonce to place the lifts in position from opposite sides.

Another object is to ,constructamachine in which as much of the operation as possible will be automatic, leaving the operirtfitrs .handsfree at all tlmes to assemble the 1- s.

Another objectis to construct the machine sothat the lifts may be automatically fastened together when assembled, and clamped while being, fastened.

Another object is to construct the machme'so that the use of the necessarypaste will not ,clog'up. and interfere'with the bearlegs and guides, and toarrange the elements ofthe mechanism so that wear and friction will be reduced to a minimum.

Further objects will appear from the detail description taken in. connection with the accompanying drawings in which:

Figure 1 is a side elevation partlyin section showing one embodiment of this ,invention, Fig. 2 is .a front elevation, Fig. 3 is a plan, Fig. 4 is a detail section on the line 44 Fig. 1, and Fig. 5 is a detailof the clutch mechanism.

In accordancewith this invention the lifts are assembled on a supporter. table. against asultable gage or positioning stop. After the lifts are thusassembled a fastener inserting mechanism .is moved into operative relation, with respect to the. assembled lifts todrive a fastener therein. The operation, after the liftshave been assembled is preferably entirely automatic, the .fastener insertmg mechanism being moved into position automatically upon the depression 0 a starting lever or treadle, a fastener being. driven, and the fastener. insertingmechanism being automatically returned to, initial Referring to the accompanying drawings,

designates a suitable support or table, and 11 a breast gage or stop ,which is adjustably mounted on the table and arranged to be locked in adjusted position by means of a clamping screw 12 engaginga slot in the gage. The gage is preferably provided with graduations (not shown) forming a scale for the height of the assembled heel blank. A pair of guides 13 are mounted on the table so as to slidingly support a carrier v by means of clamping screws 17 extending through slots cut in the flanges 18 on the block and threaded into tapped holes in the front face of the carrier. A driver bar 19 is sup orted and guided in bearings 20 forme on the carrier, and this driver bar has secured thereto a driver 21'which works in a driver passage cut in the nail block. A cam roll 22 on the driver bar is engaged by a driver cam 23 of well known construction which is secured to and driven by a shaft 24 mounted in bearings formed in the head. The upper end 25 of the driver bar is engaged by a lever 26 which is under the tension of a sprin 27 The driver 21 is clamped in the drlver bar in the usual manner by. means of a set screw 28 so that the driver may be adjusted with respect to and with the nail block by adjusting the driver in the driver bar. The lower limit of the stroke of the driver may also be varied by adjusting the collar 29 on the bar 19 in any suitable manner. Such adjustments are well known and need not be described in detail.

A clamp or lift engaging member 31 is supported by the carrier underneath the nail block. This clampv is provided with a pair of shanks 32 guided in the carrier and provided with coiled springs tending normally to force the clamp away from the carrier. The outward movement of the clamp is limited by a pin or screw 34 engaging a slot in one shank. The forward face of the clamp is rounded and beveled to conform to the backs of the assembled provided with bearings for a main driving shaft 36 which has loosely mounted thereon.

a belt pulley 37. A jaw clutch is arranged to clutch the shaft with the pulley and comprises a jaw 38 secured to the pulley, and a coiiperating jaw 39 splined on the shaft and pressed into engagement with the jaw 38 by means of a spring 40. A pin 41 on the jaw 39 is arranged to be engaged by a clutch lever 42 which is pivoted at 43 and is under the tension of a spring 44 tending to move it in a counter-clockwise direction Fig. 5. A pin or lug 45 connected to the lever 42 is arranged to be engaged by a toe 46 on a treadle operated rod 47, which is mounted in a bearing 48 on the pedestal 35 and is normally moved downward by a spring 49. A pin or lug 50 on the pedestal 35 is arranged to be engaged by a cam lug 51 on the rod 47. The rod 47 is mounted for lateral movement in the guide 48 and normally maintained in the position shown by means of a leaf spring 48.

The clutch above described is of the sin gle revolution type and is arranged to automatically stop the shaft after one revolution is completed, whether the treadle is released or is maintained in depressed position. The operation will'be obvious. As the treadle rod 47 is raised, the clutch lever 42 will be moved in a clockwise direction so as to release the pin 41 and permit the clutch jaws to engage. During the upward movement of the treadle rod, the engagement of the cam lug 51 with the fixed pin 50 will move the treadle rod laterally so as 'to move the toe 46 out of engagement with the cam 45 releasing the clutch lever, which under the action of its spring will be thrown inwardly, so that the pin 41 will be engaged by the cam on the clutch lever, causing the clutch jaws to be thrown out of engagement and the shaft 36 arrested after one revolution has been completed. When the treadle is again released the toe 46 will snap over the in 45 and will return to initial position as s own in the drawings.

The shaft. 24 has an extension 52 which has a splined connection with the shaft 36 as shown in Fig. 1, whereby the carrier may be moved axially of the shaft without breaking the driving connection. A cam 53 is secured to the shaft 24 in a recess in the head or carrier. This cam is provided with a cam groove 54, of substantially the form shown in the drawings, which is engaged by a cam roll mounted in thearm 55 of a double armed lever journaled at 56 on the head.

,The other arm 57 of the lever has a pivotal connection with one end of a link 58 the other end of which is pivoted at 59 to the pedestal 35.

' Nail loading and feeding mechanism of usual construction is supported on the pedestal 35 and comprises a rotating nail loading drum, 2. raceway and a nail separator. The main casing of the nail loader is indicated at 60 and is shown as provided with a filling hopper 61. A drum 62 is pro vided with the usual nail elevators and with a shaft which is driven from the shaft 36 by means of a=belt 63 passing over pulleys lhe nail tube is preferably of flexible conthe-end of the revolution be automatically 64 and 65 on the drum and main driving driver drops into the driver passage or the carrier nears the initial position, the

shaft respectively. A raceway 66 of usual construction extends into the loader casing and is supported thereby, and is provided at its lower end with a nail passage and a separator 67 arranged to feed the nails one by one to the nail passage. -'The separator is moved in one direction by means of a spring 68-and in the opposite direction by means of a cam lug 70 on the cam 53 en gaging-the end69 of the separator. This separator is of ordinary construction and operates when the carrier or head returns to its initial or rearward position, as hereinafter described, to feed a' fastener to the funnel shaped end ,of a nail tube 71 which guides the fastener to the driver passage.

struction so as tobe adjustable with the nail block in a manner well known to those skilled in the art. 5

The operation of the machine will now be described.

When the machine is at rest with the drivi ing shaft disconnected, the head or carrie is in rearward position away from the gage 11 and the parts will be in the position shown in the drawings. ihe driver is at this time in depressed-position, and the last rearward movement of the carrier will have actuated the separator to drop a nail in the nail tube 71, andthis nail will be resting against the side face of thedriver. If there is no nail in the nail tube then the separator can initially be operated manually to -release a single nail. After the lifts have been positioned in assembled relation against the gage11,'the treadle is depressed so as to operate the clutch in the manner described. "lhe cam'53 will now "cooperate through the lever and link connection with the rigid abutment 59 to move the entire carrier forwardly with the nail block over the assembled lifts. This will cause the yieldingly mounted clamp 31 to engage the back of the lifts and firmly clamp the lifts together. After the carrier has been moved toforwa'rd position, it will remain at rest during a half revolution of the shaft, and during this half revolution the cam 23 will operate to raise and release the driver. The nail or fastener which rests against-the throat piece as the driver is raised, and is driven in the assembled lifts by the descent of the driver. During the next quarter revolution the carrier is returned to initial position away from the assembled lifts, and as separator will be engaged by the cam lug 70 to separateand drop another nail into the nail tube. The driving shaft 36 will at arrested and the parts will come to rest driver down, and a separated nai1 ;resting against the driver. Y ltwillr be understood that during the revolution of theshaft the nail loader has been operated to load .nalls or fasteners in the-raceway. m 'In the operation ofassembling and securing the assei'nbled lifts together, the lifts will be piled-on the table andagainst gage 'llfrom right and left. Preferably paste or cement brushes B -driven: by -pulley- 6 are also mounted onthe-table, andthese brushes may run continuously in paste: re-

ceptacles C below the topof the table: as

shown in the drawings. The operator will stand in front of the table and pile lthe liftsogo inplace using both hands. In assembling he will pass 'the-l'ifts over the brushes B to apply a coating of cement or pastethereto, and then move them toxassembled position from the sides. Naturally inquick-opera-eag tion the movement of the lift-from the time it is picked :up until it is placed in position will be practically a- -con'tinuons sideward movement, the liiftsbeing ,qui'cklypassed over the brush-andKby continuous--mozve-reo :ment against the breast gage. "This is possible in view of the fact that the -table, in

- front of, laterally of and' above the-gage, .is entirely clear;- the assemblingcam therefore be performed: very rapidly. aA-fterthe' leiftsea have been assembled, the fastener inserting mechanism is moved intoand out of operative position above the assembled! ilifts automatically. In the imovement of-!the carrier toward :thegageill, theclam i3lzwillvaoo first yieldinglyi engage the-backs :0 the lifts, and the fastener 1 is driven while the lifts are thus clamped between thebreast gage 11 and the clamp31. This insures that the cemented "joints will befirm and prevents whe assembled lifts from oeingrshattered apart while the fastener isidriven. -'lhe-.hands of the operator are freeat all times andwit is not necessary for him to. stop andi-pickzup a .hammerand. drive a long fast'ener. "Thistle is quite=an advantage, in view of the fact that the operators hands are covered with paste rendering the :manipulation of the hammer and nail. exceedingly diflicult where the fastening operation. is performed by hand, and-in addition saving animmense .amount of. time. "The only real manual operation is the I assembling;v the fastening operation and the return of the carrierbeing performed automatically =upon depression '120 of the-treadle; 1

In order toadjust themachinewforheels of different-sizes,- the breast-gage' can be adjusted onthe table, and the nail block-together with thesdrivercanalso be adjusted dmi toward and from the: table. The adjustment for varying the relation-.ofrdriving mechanism andv the breast gage .need menely be a relative adjustment .and'itherefore' the with the carrier in initial position, with the adjustment maybe in the 1ink 58er-insome t3e cams 23 and 53 are so proportioned and other part of the connection of the carriage with the rigid abutment 59. However, by adjusting the breast gage, not enly may the adjustments be very much simplified, but the connections driving the carrier can be fixed and permanent connections, so that the carrier-has a fixed stroke. It will be noted that the back gage 31 is automatically adjusted with respect to both the fastener insert-ing mechanism and the breast gage. The

timed that the driver is'operated while the carrier islat rest. By means of this construction there is no torsional strain on the in view of the fact that it lengthens the life of the driver spring. This also enables the feedin mechanism for-the fasteners to be sim li ed -when using a stationary nail loa er and feeder. Q

It will be noted that the ositioning gage 11 which positions the li s in assembled relation remains with the assembled lifts at rest, while the fastener inserting mechanism is movable into and out of position above the lifts. This has many advantages over a construction in which the assembled lifts are moved underneath the fastener in- "sertin mechanism. By means of this constructlon the table laterally of the assembling portion. or space is left entirely clear and smooth the assembling can therefore be pgrformedrquickly. There are no guides to clogged up with paste. The lifts are better supported and are better maintained in assembled relation after they are once assembled since the remain at rest. Where the assembled li ts are moved quickly to position the inertia efiect is liable to work to a disadvantage in shaking the assembled lifts loose. In the present construction after the lifts have been assembled the operator can maintain them in position by placing his fingers upon opposite sides of the assembled lifts while they are being fastened.

In the specific embodiment shown the stationary gage is the breast gage while the other one is the back gage. While this is the most advantageous construction it will be obvious that the positions of these gages may be reversed.- It is also obvious that various changes may be made the details of construction without departmg from the spirit of this invention, and it is therefore to be understood that this invention is not to be limited to the specific construction shown and described.
